My car will smoke the tires if i powerbrake it

 

some one probobly put a 262 baby lt1 in your car before you bought it like the 1 i bought .I bought a 95 Z28 and the guy i bought it from put a 262 baby lt1 in it thinking it was a 350 lt1 and with 2.73 rear end it would not turn the tires neather.So i bought a 96 lt1 out of a recked ss and put bbk headers and a 2100 stall also on it tbbypass and with 2.73 rear have ran a best 13:97 at 100.4 miles an hour.thats kicken with 2.73 rear. and it will burn through 1st and 150 feet in second.very impresive.next is 3.73 gears .So i would check to make sure its a lt1 350 they look just alike .Z28 lt1s come with aluminum heads 262 motors comes with iron heads.

 

when you put a carbed intake on a lt1 what do you do about the Ignition do you stick with the opti spark and if you do what about timing advance how does it all work with a carb

 

You should be able to run a standard distributor on it...as the LT1 cams still have the rear distributor drive gear on them.

 

ooo ok thanks for the info i did not know that

 

Its a 350 LT1

 

i hope you check to see if you really have a 5.7,like mentioned before it could be that 4.3 caprice motor,the heads do interchange so dont go by that method check on the drivers side of the motor in the rear just below the head and it should be stamped 5.7L.....it would really suck to buy the carb,manifold,dist.,do all that conversion work to find out its a worse turd than you started with!

 

Is this a common swap to change out the 350? Its makin me paranoid now even though i have no reason to suspect mine was swapped.

 

not a common swap at all,someone may have got the car cheap cause the motor was dead and found that motor got it runnin good enuff to sell it!
don't give up on the efi,find out what you are really workin with!

 

What all will have to be done and whats the total cost.
My stock injectors couldn't complete with a Holly 750DP. Also, you can put nitrous on the engine for much cheaper and more powerful shots if you use a carb.
